Novant Health Inc., Wake Forest Baptist Health and the Forsyth County Department of Public Health are offering more walk-in vaccination slots, as experts say the drop in requests for the vaccine may slow herd immunity. Novant is providing walk-in vaccinations at its Hanes Mall site from 7 a.m. to 7 p.m. weekdays. The number of walk-in slots is subject to available supply each day. People with appointments can opt for a walk-in appointment or reschedule for an earlier slot at www.GetVaccinated.org. Walk-in vaccinations allow people to get their doses "in the flow of their lives," said Dr. David Priest, an infectious disease expert with Novant.
